In another further configuration, described at least two rollers that are arranged on cable roll and clean between the scraper comprise a string action roller, and the effective length of this string action roller is determined by going here and there width.
In another further configuration, described at least two rollers that are arranged on cable roll and clean between the scraper comprise a squeegee, and this squeegee rests on cable roll and the string action roller, and the effective length of this squeegee is determined by the length of the body of roll of this squeegee.At this, squeegee is transfixion in the axial direction.
Description of drawings
From following description of a preferred embodiment and accompanying drawing, obtain according on other structure of printing machine of the present invention and function on favourable further configuration.Accompanying drawing is represented:
Fig. 1 anilox inking unit,
The roller group of Fig. 2 anilox inking unit, and
The corresponding roller group of direction of observation III among Fig. 3 and Fig. 2.
The specific embodiment
Fig. 1 shows a printing machine 1 with the printing equipment 2 that is used for offset lithography.Printing equipment 2 comprises an anilox inking unit 3, and this anilox inking unit has a cable roll 4 and an inking roller 5.In addition, printing equipment 2 comprises a plate cylinder 6, a blanket cylinder 7 and an impression cylinder 8.In printing work, inking roller 5 is opened at roll extrusion on the plate cylinder 6 and page or leaf to be printed and is transmitted on impression cylinder 8.
Printing ink input unit 9 rests on the cable roll 4, so that give this cable roll input printing-ink.Printing ink input unit 9 comprises an ink containment chamber and a metering scraper, and printing-ink inputs to cable roll 4 from this ink containment chamber, and this metering scraper is wiped unnecessary printing-ink off from cable roll 4.
In cleaning model, first roller 11 rests on the inking roller 5, second roller 12 rest on the cable roll 4 and the 3rd roller 13 on.At this, the 4th roller 14 rests on first roller 11, and other roller 15 can rest on cable roll 4 and the 3rd roller 13.Second roller 12 and the other roller 15 that exists in case of necessity are squeegees, promptly use the roller of the roller shell coating of rubber elasticity.The 3rd roller 13 is string action rollers, and this string action roller carries out axial reciprocating motion.
Being provided with one is used for cleaning agent spraying first injection apparatus 16 and second injection apparatus 17 that is used for then flushing water being ejected on the 4th roller 14 to first roller 11.Injection apparatus 16 constitutes an input unit 18 that is used to import washing agent.
A discharger 19 that is used to discharge washing agent-printing-ink mixture rests on the 3rd roller 13.Discharger 19 comprises a cleaning scraper 20 and a feeder 21 that is used to collect the mixture of being wiped off that washing agent-printing-ink mixture is wiped off from the 3rd roller 13.
Cleaning is as follows: the washing agent that is ejected on first roller 11 is being measured in the roller gap that the 4th roller 14 forms by first roller 11 and is being transferred to inking roller 5 with the form of homogeneous film from first roller 11.Washing agent is transferred to cable roll 4 from inking roller 5.At this, printing ink input unit 9 can be from plate cylinder 6 trippings from cable roll 4 trippings and inking roller 5.The washing agent that is applied on inking roller 5 and the cable roll 4 makes printing ink remnants break away from from these rollers 4,5, and these printing ink remnants remove and be transferred to the 3rd roller 13 by second roller 12 and other roller 15 (if present) from cable roll 4 then.
Fig. 2 shows the explanatory view of the roller group that is made of roller 4,5,11,12 and 13, and wherein, for clearer reason, these rollers illustrate on a straight center line, promptly ignore between the contact point of roller at the actual angle of circumference shown in Fig. 1.
Fig. 3 shows the side view of the roller group among Fig. 2, and this view allows to see effective roller length of representing with the dimension arrow symbol of roller 5,11,12 and 13.Cable roll 4 has maximum axial length in whole rollers of roller group.The effective length L of first roller 11
11The axial length of the body of roll by first roller 11 is determined.Fixing unshowned axle journal in the accompanying drawing on this body of roll in the accompanying drawings.The effective length L of inking roller 5
5Determine by the axial length that is tightened in the blanket 24 on the inking roller 5, referring to Fig. 1.The effective length L of second roller 12
12The axial length at the body of roll shown in Fig. 35,26 by second roller 12 defines.
Effective axial length L of the 3rd roller 13
13Two reversal points of the axial motion motion 23 by being present in the 3rd roller 13 or the distance between the stop are determined.This distance is also referred to as the moving width L of string
13And length 1 greater than the body of roll of the 3rd roller 13.
The effective length L of inking roller 5
5Effective length L greater than first roller 11
11The effective length L of second roller 12
12Effective length L greater than inking roller 5
5If other roller 15 exists, referring to Fig. 1, then this other roller can be identical with second roller, 12 structures, and thus, the effective length of other roller 15 is also greater than the effective length of inking roller 5.The effective length L of second roller 12
12Effective length L than inking roller 5
5Greatly preferred 20mm at the most.The effective length L of the 3rd roller 13
13Effective length L greater than second roller 12
12
By being arranged on before the cable roll 5 and the effective length of afterwards roller increases up to the position of striking off of washing agent from the introducing position of washing agent, forming near the axial region that is in the edge and is not rolled across of cable roll 4 that liquid ring 25 can be avoided or on enough degree, minimizing at least by inking roller 5.In the trouble of getting rid of and dripping and causing thus that on cable roll 5, forms the washing agent-printing-ink mixture of this liquid ring 25 under the situation of no described counter-measure, for example pollute the adjacent machines part and can be avoided thus.The length grading of roller 5,11,12,13 is selected like this: make to guarantee that washing agent evenly distributes and washing agent-printing-ink mixture is evenly failed away.
Cancellation first roller 11, the 4th roller 14 and configuration be the substitute is the injection apparatus that exists a damping device and some configurations to give damping device to the injection apparatus 16,17 of these rollers 11,14 in the unshowned flexible program in an accompanying drawing.
Describe and be illustrated by drawings layout and structure that the injection apparatus of damping device is given in this damping device and configuration among DE 102005056812 A1 (corresponding to US 2006130680 A1).Thus, foregoing two documents are included (by reference and in conjunction with) in the disclosure of the specification.
The gap bridge roller that exists in this flexible program (referring to the reference number 22 among DE 102005056812 A1 or the US2006130680 A1) is so replace first roller of being cancelled 11 in Fig. 2 and Fig. 3.The gap bridge roller rests on the inking roller 5 in cleaning model and has effective length L with first roller 11
11Equally big effective length.Therefore, the effective length L of inking roller 5
5Effective length greater than the gap bridge roller.The effective length of gap bridge roller can only be determined by the length of its body of roll, preferably determines by the moving width of the string of gap bridge roller, promptly determines by the distance between moving two stops that move of the string of gap bridge roller.
